About converting WGS 84 to NAD83
Converting from WGS 84 (EPSG:4326) to NAD83 (EPSG:4269) is the conversion needed to align GPS-derived data with U.S. federal geospatial datasets. NAD83 was originally aligned with ITRF at epoch 1986; modern WGS 84 tracks ITRF and has since diverged by 1-2 m due to North American plate motion.
This converter applies a Helmert seven-parameter transformation accurate to a few centimetres against NAD83(CORS96) — adequate for most analytical work. For surveying-grade or cadastral work specify a particular NAD83 realisation (NAD83(2011) is EPSG:6318) and apply the published Helmert parameters for that realisation.
Why people convert EPSG:4326 to EPSG:4269
- Aligning commercial GPS data with USGS / Census / NHD datasets
- Importing aerial-photo control into NAD83 mapping
- State Plane projections (which all use NAD83)
- Generating products for U.S. federal data exchange

The EPSG dataset defines official transformation parameters for the reverse direction. See NAD83 to WGS 84 — the parameters are invertible.
Convert EPSG:4326 to EPSG:4269 in code
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4326", "EPSG:4269", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
print(x, y)Target: EPSG:4269 — NAD83

Frequently asked questions
- Are NAD83 and WGS 84 interchangeable?
- Not for sub-metre work. They differ by 1-2 m across CONUS due to plate motion. For most visualisation use the difference is invisible; for surveying it must be modelled.
- How accurate is converting WGS 84 to NAD83?
- Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift transformation in a desktop GIS.
- Does my data leave the browser when I use this converter?
- No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
